Remove the standing water first, then use mechanical methods like cleaning the stopper, plunging, or using a drain snake to clear the blockage.

To unclog a bathroom sink with standing water, first bail out the excess water using a cup or small container to improve access and prevent spills. Once the water is removed, start with the simplest mechanical methods: remove and clean the drain stopper, as hair and soap scum often collect there. If the clog persists, use a plunger, ensuring you cover the sink's overflow hole with a wet cloth to maintain suction. For deeper blockages, use a plastic drain snake to pull out debris, or remove and clean the P-trap (the U-shaped pipe under the sink) while keeping a bucket underneath to catch residual water. Natural solutions like baking soda and vinegar can help with minor organic buildup.
